NH4I will completely dissolve in ammonium and iodide ions: of which I-is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6).
Acids and Bases. BrÃ¸nsted acids are proton donors, and BrÃ¸nsted bases are proton. acceptors. Examples of BrÃ¸nsted acids: HCl, HBr, H2SO4, HOH, H3O+, +NH. 4, NH3, CH3CO2H, HâCH2COCH3, HâCâ¡CH, HâCH3. Examples of. BrÃ¸nsted bases: anything with a lone pair. BrÃ¸nsted acids are. generally neutral or cationic, and BrÃ¸nsted bases are generally neutral. or anionic. Some compounds (H2O, NH3, acetone) can be either acids. or bases. Lewis acids are electron pair acceptors, and Lewis bases are. electron pair donors. The set of Lewis and BrÃ¸nsted bases are. essentially identical, but many Lewis acids exist that are not proton. donors.
